SIDE BERING.

riez-anso.

Application led January 7, 1916.

Z 1o all whom t may concern Be itknown that I, FLMYR A. LAUGHLIN, a citizen of the United States of America, and a resident of Oregon, county of Ogle, and State of Illinois, have invented certain new and. useful lmprovements in Side Bearings, of which the following is a specifica tion.

The main objects of this invention are to provide an improved form of side bearing for railway cars; to provide in a trunnioned roller side bearing an improved construction and arrangement of the housing whereby a section of the housing may be removed to permit the ready insertion or removal of the trunnioned roller, the arrangement being such as to avoid impairment of the strength of the housing at its outboa rd side where it is subjected to heavy strain; to provide an improved arrangement for securing the wear plate in place; and to provide an improved construction of the trunnion raceways whereby the roller will normally return by gravity to a medial position and whereby the wear on the roller due to vibration and pounding will be distributed over the periphery thereof.

A n illustrative embedii'nent of this invention is shown in the accompanying drawings, in which:

Figure 1 is a side elevation of the improved railway side bearing illustrating a specitc arrangement embodying two rollers. Fig. 2 is a bottom plan of one end of the same. Fig. 3 is a transverse section taken on the line A-A of Fig. 1. Fig. Llis a longitudinal section taken on the line RMB of Fig. 3. Fig. 5 is a longitudinal section detail taken. on the line C-C of Fig. 3. Fig. 6 is a fragmentary detail of the housing taken on the line D-D of Fig. 4A. Fig. 7 is a fragmentary detail taken on the line lil-E of Fig. 8, showing how one end of the wear plate is supported. Fig. 8 is a detail in elevation of one of the removable sections.

In the construction shown in the drawings, the supporting frame or housing 1 is in the form of a hollow malleable casting open at the bottom to provide a roller runway 2 between the vertical side walls 3 and 4.-.

Rollers 5 are mounted to travel in the runways 2, being pro-vided with trunnions 6 and 7 extending into the trunnion guide- Specication of Letters Patent.

ways 8 and 9 formed in the respective walls 3 and 4. The trunnion guide-ways 8 and 9 provide inwardly disposed ledges 10 and 11 overhanging the trunnions and adapted to engage the same for supporting the roller when it is out of contact with the wear plate 12. The under sides of the upper guide surfaces or ledges 10 are inclined downwardly toward their ends so that when the roller approaches either limit of its travel, the load will be transferred from the periphery of the roller to the trunnions and the car will be slightly elevated with respect to the truck, as more fully described and claimed in my Patent No. 1,163,020, dated December 7, 1915.

The lower ledges or guide surfaces are of wavelike form and have a series of transverse ridges 13 and depressions 14 extending throughout the greater part of the length of said ledges. One ridge is preferably located at a point substantially midway between the ends of the trunnion guide-ways so that the rollers will come to rest at one side or the other of a central position. This distributes the wear on the rollers due to pounding` while the rollers are idle.

The outer shoulders 15 on the ledges 11 are preferably made square and are located slightly outward of the center of the roller when the latter is at the limit of its travel so that the roller will roll inward from shoulder 15 toward a central position, as fully explained in my Patent No. 1,131,252, dated March 9, 1915. This construction of the upper surfaces of the ledges 11 also tends to prevent the roller from rolling toward the' ends of the runways at times when the roller is relieved of the load.

A section 16 is made removable from the wall et of the housing to allow for the insertion or removal of the roller 5. The section 16 comprises a part 17 of the side of the wall 4- and a part 18 of the ledge 11. The width of the part 17 is substantially equal to the diameter of the trunnion 7 and that of the section 1S is substantially equal to the diameter of the roller 5. When this section is removed, the roller 5 may be shifted aXially so that the trunnion 7 projects through the opening formed by the removal of part 17 of the wall t and the roller 5 moves into the space formed by the removal of the part 18 from the ledge 11, as indicated in dotted outline in Fig. 3. This removes the trunnion 6 from the trunnion guide-way 8 so that the roller may be readily withdrawn from the housing. The section 16 is separated from the wall el on planes 19 and 20, converging axially outward, as indicated in Fig; 2, so that when the' sections are set in place any pressure thereon from the inside tends to wedge them more firmly in position.

Shoulders 21 formed on the part 18 engage theadjacent part of the wall 4 and coact with the tapered sides of the section 16 in securing the'latter in place and enable it to be securely fastened by a single rivet 211 connecting the lugs 22 and 23 on the section 16 and adjacent part of the wall 4.

rlhe wear plate 12 is held in place on the Vframe 1 by seating one end of a recess 25 in one side wall and fastening the'other end by a rivet 26. rllhe rivet is inserted through a hole 27 formed in the framel at the edge of the -wear plate so that the latter need not be perforated but is merely overlapped by one side of the rivet head 2S. lTheledge 10 at that side of the runway is cut out at 31 (Fig. 6) to allow for the insertion of the rivet and the riveting` tool.

The frame 1 is provided with the usual apertured flanges 30 by means of which the bearing may be attached to the car bolster in the usual manner.
